Drillhole planning is at an advanced stage within the Simuku porphyry copper system. Simuku is host to an Inferred Resource of 200 million tonnes grading 0.36% copper. A number of drill hole sites have been pegged and checked for ground safety requirements between the Misili prospect and one kilometre further north at the Nayam prospect (refer to Figure 1).
At the Nayam prospect, within the area of the Simuku Inferred Resource, historical drillhole SMD26 intersected 282 metres grading 0.45% copper from 18 metres depth. In the opposite direction to the south-west, historical hole SMD19 intersected 93 metres grading 0.59% copper from 8 metres depth including 18 metres of 1.0% copper from 18 metres depth. These zones of higher copper mineralisation are related to potassic (magnetite-biotite-anhydrite) altered microdiorite intrusions.
In addition to the advanced Simuku deposit, the Kulu prospect, 5.5 kilometres to the eastsoutheast has anomalous grades of copper in rock samples over an area of 800 metres by 600 metres (refer to Figure 2). The geochemistry indicates a zonation effect of copper-molybdenumgold at the centre with outer lead and zinc to the northwest, possibly indicating a larger porphyry copper system at depth.
